Incinerators

Abstract

An incinerator apparatus consists of a container with an inlet for gaseous or particulate, combustible material together with combustion air, and has an outlet for combustion products, the walls of the container, and possible walls disposed in the interior of the container, being designed for the generation or vortices in the material flowing through the container from the inlet to the outlet. At least the surfaces of the walls facing the inner space of the container include a substance which has the capability to catalyze the oxidation of carbon and carbon compounds in the combustion in the apparatus.

What I claim and desire to secure by Letters Patent is: 
     
       1. Incinerator apparatus comprising a casing including a substantially cylindrical mantle, an inlet wall sealing one end of said mantle and the defining a central inlet opening for gaseous or particulate, combustible material together with combustion air, an outlet wall sealing the other end of said mantle and defining a central outlet opening for combustion products, and a partition wall within said casing dividing the interior of said casing into an inlet chamber adjacent said inlet wall and an outlet chamber adjacent said outlet wall, said inlet wall having, on its side facing the inlet chamber, an annular depression surrounding the inlet opening, the defining surface of the depression being smoothly rounded in cross-section, said outlet wall being domeshaped with the concave side facing the outlet chamber, the central portion of said partition wall being formed as a conical mantle whose outside faces the outlet chamber and whose inside faces the inlet chamber, and said partition wall having at least three edge recesses distributed around the periphery of said partition wall and defining together with said cylindrical mantle communication passages between the inlet and outlet chambers. 
     
     
       2. Apparatus according to claim 1, wherein said edge recesses of said partition wall extend obliquely through said partition wall. 
     
     
       3. Apparatus according to claim 1, wherein at least one of said mantle, said inlet wall, said outlet wall, and said partition wall contains a material having the capability to catalyze the oxidation of carbon and carbon compounds in the combustion in the apparatus.
